is in decline. researchers at the australian institute of marine science say the reef has lost half of its coral cover over the past 27 years. there are multiple causes, including a destructive kind of starfish shown here. we look at what's behind it and what's at stake-- in australia and around the world-- with nancy knowlton, a coral reef biologist and a chair of marine science at the smithsonian national museum of natural history here in washington. welcome. >> thanks. how has all of this coral died off? do we know what's causing it? is it all that... >> it's not all the star fish. the star fish is about 42%. typhoons, big strong storms another 48% and then coral bleaching is the remaining 10% which is caused whenever the water gets too hot. >> ifill: so this is human causedded? >> yes. most of it is human caused. i mean a coral reef naturally goes through cycles of up and down. but it shouldn't be declining by half over course of 27 years. >> ifill: i feel like we have talked before about the declining coral cover. but not... but i'm wondering whether it's now picking up speed or whether thi
of marine science says the pace of damages kicking up. cyclones of predatory starfish are the main causes along with: gas shipments and global warming. >> coral reefs provide the breeding ground for countless species of fish. the great barrier reef is no exception. commercial fishing is now mostly banned across much of the area. three 6 cents more than 2,600 kilometers along the us trillion coast. the northern part of the refinements largely intact. it is the southern part scientists are worried about. severe storms are said to have cost nearly 50 percent -- said to have caused nearly 50% of the damage. a further 40% was caused by starfish that feed on the coral. one species, the crown of thorns, has proven especially deadly for the coral cover. >> we believe if we can take action on one of the things we can directly control, the crown of thorns starfish, it may leave the reef in a position where it can better withstand some of the climatic impact spite cyclone and coral bleaching. >> regardless of what is causing the damage, brain biologists say action needs to be taken now to save the r
of systems all of which are so important to the asia-pacific region. and we'll continue all of our science and technology investments across the board. the third reason why we can carry out the rebalance is that we're shifting our posture forward and into the asia-pacific region; that is, not what we have, but where we put it is also changing. by 2020 we will have shifted 60% of our naval assets to the pacific. that's an historic change for the be united states navy. the marine corps will have up to 2500 marines on rotation in australia, we will have four la toral combat ships stationed forward in singapore, i was just aboard both in san diego last week, and we'll proceed fully to build out our military presence on guam and surrounding areas, which is an important strategic hub for the western pacific. we will begin to rotate b-1 bombers into the region augmenting the b-52 bombers already on continuous rotation. we've already deployed f-22s to kadima air force base in japan, and we will deploy the f-35 joint strike fighter to the region. differently, we're sending our newest assets to the
right by medical science, is really critical for achieving health and preventing these diseases. so the green new deal is a win/win win because it gets us to clean energy which can stop the climate crisis, jump start our economy, creating three times as many jobs as every dollar spent in the fossil fuel economy, and it puts us back to work. so it's a win/win win all around. host: dawn, joining us from oxford, alabama with dr. jill stein, last call. good morning to you. caller: good morning. i kind of agree with an awful lot of what you said about the cause of all this. but the one thing that you admitted and i'm cureuse about, what would -- kaoeurous about, what would make a banker with the subprime mortgage, what would make him -- which the whole goal is to make money, as much as he can, what would make a banker loan money to somebody that he knows was not going to be able to pay him back? and then do they just think -- get a meeting and say we're going to create these instances where we're going to loan money for people to buyouts, paopl that can't pay it back and sell it to someb
the most government funded research to push the boundaries of science and technology so our best innovators and the entrepreneurs could pluck them and start these companies. if you think about that is a formula for success, and education we now -- well, roughly 30% of high school students drop out of high school. we used to lead the world in college graduates coming out of high school. we no longer do that. on infrastructure, according to the american society of civil engineers we are now $2 trillion in deficit in terms of infrastructure. immigration we have a policy to get a great education and then get the hell out of our country. we are fighting on the simplest h-1b issues that are so vital for our future strength. fourth, the rules for incentivizing risk-taking and preventing recklessness. i don't think that we have in any way remedied that the way we want and on the government funded research if it looks like an ekg heading for a heart attack. i don't know if they are relative to what. all i know is in the things that have historically made us great, on each one of those i see us not g
. there is some corals that live for many thousands of yeernz we found through some of the science we do we can drill holes down to the center of the corals and look at annual growth rings and we can look at when, in fact, when the first agriculture in australia happened, we saw a change in the type of chemistry that the annual growth rings and coral were depositing. so we have seen a chronology of increased siltation, of increased fertilization, of
isn't rocket science. it's just common sense. from td ameritrade. >>> we've heard it all morning long it and still makes us jump. a huge 747 crashing in the dessert, by remote control, all part of the discover channel's new "curiosity" series where a controlled experiment was captured by 40 cameras and sensors to give researchers what happens during a crash atlantaing. >> it airs on discovery channel this sunday night at 9 p.m. two top experts are here with us now, accident investigator dr. tom barth and dr. cindy bir. >> thank you for being with us this morning. we're very excited about this. >> i asked you, dr. bir, earlier, have you ever attempted to do this before and you said you have. this took over four years to plan. why did you want to crash a plane? >> we were -- i was approached by a production company to do this about four years ago. i think tom and i were approached about the same sometime. and was just such an interesting project. i didn't attempt it before, but it was attempted back in '84. and they had lessons learned. we have new technology. so, it was a wonderful opp
. and then for these, these are the breakthrough awards, these are based fully on science, innovation, products that have done something that no other product has done before. and we actually work it out with te dermatologists and chemists. we make sure these are legit. >> they've been scientifically tested and approved. >> completely. >> let's take a look at, starting first with the real weightless foundation from georgio armani, apparently five different oils instead of water or powder. >> and you know how foundation can feel thick and heavy, this one uses all the different oils which you think would be greasy, but they're really light oils, they evaporate on the skin, so you get the pure pigment. it's maestro foundation. >> amazing. >> those who suffer from r rosasia, there is no medical cure for this, but you did find this cream can be helpful. >> there's no cream over the counter for this. and what happens is there's too many blood cells underneath the surface of the skin and too reactive. so this aven cream, it's french. >> anti-redness. >> right. >> for chronic redness. it has a protein
the subjectivity out of it and you put science around it. so it gives you a benchmark for the products that you have. so when we start looking at that, what we did was we said okay, what are some other alternatives? how can we horne into this as -- honey into this -- hone into this aspect of this particular product. we looked at things from the food industry, for instance. when we did that we came up with the clean stem fluid which is sourced as you said entirely from the fluid industry. what that did by developing those right off the bat, we had two or three orders magnitude stepdown in the numbers. >> numbers of what? >> it's a relative ranking. if you look at one product just in round numbers, let's say it's got an 800, which is what we have been using, some are down to 300 this. >> in terms of what? >> the effects of health, safety and environmental standpoint. >> researching and developing the new recipes for fracking is very expensive. tens of millions of dollars i imagine. >> yes, sir. >> the company believes the existing process, the ones they have been using for years is safe. why is h
